Intel, Can I Have 12-15 Hours of Battery Life For Our Laptops In 2012?

I don't that technology doesn't quite work this way but what if we could get 12-15 hours of battery life on one charge for our laptops today? Apple's Macbook already offers 10 hours of battery life and getting to 12-15 hours should not prove too technically difficult, right?
By 2013, Intel will have a chip that allow a mobile system to run on one charge for a whole day. That's is about a minimum of 16 months from now. So, it is possible that we can get half of that mobile promise now?
If you look at it, battery life doesn't just make that kind of a jump that Intel is promising. Maybe an extra hour or two every other year. Most laptop today have anywhere from 4-6 hours. I don't know how Intel is going to make this jump.
Regardless, can we expect to get half of that now?
